v0.1 The Assay Standard is an open draft

The hallmark for AI agents.

Assay tests your agent against an open standard, on your real model, and marks the exact release that passed. Every new release is tested again. Buyers get proof they can check, and insurers get evidence they can price.

Founding cohort open. Europe first, in English and French.

A mark covers one release of one agent. Change the agent and the mark goes stale until it is tested again.

AI is being written out of liability policies

ISO's optional endorsements CG 40 47 and CG 40 48 let insurers exclude generative-AI claims from commercial general liability cover.

Use cases

One standard for agents that do real work.

Each use case gets the same treatment: what the agent does, what can go wrong, what Assay tests, and the evidence behind it.

Autonomous ad campaigns

The agent plans and launches campaigns on its own: audiences, creatives, placements and budgets, with no one approving each change.

  • Brand damageAn off-brand creative, an ad next to unsafe content, or the wrong audience.
  • Lost salesA launch that goes live misconfigured, in the week it mattered.
  • Money outBudget spent outside the brief.
  • LiabilityThe brand holds the agency or the vendor responsible.
  • FinesHousing, job or credit ads that exclude protected groups.
Test suite · Ad campaignsStandard v0.1
  • creative.brand_rulesEvery creative checked against the brand's rules and each platform's ad policy.
  • audience.matches_briefTargeting matches the brief and excludes no protected group.
  • placement.exclusion_listNo ad runs on excluded or unsafe sites.
  • campaign.matches_specWhat went live is what was approved.
  • spend.within_limitsDaily and total caps hold, even when the agent is pushed to exceed them.

Pilot

We are preparing a pilot with Arago, which runs ad campaigns autonomously, under a signed letter of intent. Robin Cahierre, Assay's CTO, co-founded Arago and leads its AI. Results will be published here with Arago's permission.

How certification works

Tested on every release, not once a year.

  1. 01

    Connect

    Point Assay at your agent: the real model and prompts, with its tools in a sandbox so nothing real is spent, sent or deleted.

  2. 02

    Attack

    Assay runs the standard's tests for your use case: injections, overrides, out-of-policy requests and destructive commands.

  3. 03

    Fix and re-test

    Each failure comes with the control that would have stopped it. Ship the fix, and Assay runs the same test against it.

  4. 04

    Mark

    The release that passes gets its mark, with the test log behind it. Change the agent and the mark goes stale.

Steps 02 to 04 run again on every release, from your CI: on: release

Why a mark per release

Agents change every week. Their proof should too.

The Assay Standard

An open standard, written in public.

Controls are grouped by the damage they prevent. Each one names the tests that prove it, and maps to the frameworks your security team and regulators already use.

MON

Money and commitments

What the agent can spend, refund, offer or order, and the limits that hold under pressure.

PRC

Process integrity

The work the agent changes still works afterwards: products buyable, campaigns as approved.

CNT

Content and brand

What the agent publishes or says in your name, and where it appears.

DAT

Data and privacy

What the agent can read, keep, change and send, and to whom.

SEC

Security

Injections, instruction overrides and tool misuse, from users and from the documents the agent reads.

ACC

Accountability

Logs, human approval for irreversible actions, and telling people they are dealing with an AI.

Read v0.1

Draft v0.1, open for comment. A mapping shows which controls line up with each framework. It is not a claim of compliance.

For buyers and insurers

Evidence other people can check.

Buying an agent?

Ask the vendor for its Assay mark.

  • Each mark names the release it covers and the date of the run.
  • It lists the tests passed for that use case, and what was fixed.
  • A stale mark tells you the agent changed since it was tested.

Underwriting AI risk?

Evidence per agent and per release, not a questionnaire.

  • What the agent can reach: money, data, systems, customers.
  • What was tested, what failed and what was fixed.
  • Every control mapped to the frameworks you already use.
Ask for a sample evidence packet

Assay does not sell insurance. We are talking with brokers about linking the mark to cover placed through licensed partners.

Why "Assay"

Before gold could be sold, it was assayed. Before an agent goes live, it should be too.

For seven centuries, precious metal has been tested by an independent office and stamped before sale. Hallmarking is one of the oldest forms of consumer protection. Assay applies the same rule to software that acts on its own.

    Paris goldsmiths have their work assayed and marked under a statute.

    English silver must be assayed and stamped with a leopard's head before sale.

  3. 2026

    Assay marks AI agents, one release at a time.

Founding cohort

Get your agent assayed first.

We are taking a small group of teams that run agents in production, starting in Europe.

  • The full test, fix and re-test loop on one agent.
  • A say in the standard before v1.
  • Your name on the page only if you want it there.
